SPECIFICATION forming part of Letters Patent No. 412,810, dated October15, 18819.

Application filed May 28, 1889. Serial No. 31.2,249. (No model.)

To aZZ whom it may concern.-

. Be it known that we, JOSEPH VERCELLI and BATTIsTA GRAZIANA, both ofBoston, county of Suffolk, State of Massachusetts, have invented anImprovement in Machines for Cutting, Shaving, and Grinding Cheese, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like letters 011 the drawings representinglike parts.

This invention has forits object to construct a machine for cutting,shaving, and grinding cheese and other material.

The invention consists in the combination, with a grater, as agrating-cylinder, of a plate, said plate being partially perforated, andtwo receptacles, one of which is arranged to receive the materialfalling from the top of the plate, and the other of which to receive thematerial passing through the perforations in the plate; also, in thecombination, with the framework and top plate having an opening throughit, of a knife adapted to be moved into the opening in the top plate, sothat its cutting-edge occupies a position just above the top surface ofthe top plate, by which the cheese may be cut in thin slices or shavedoff; also, in the combination, with the top plate, of a circular sawarranged on a shaft and appearing just above the surface of the topplate, by which the cheese may be sawed in blocks or pieces; also, inother details of construction, to be hereinafter described.

Figure 1 shows in vertical section a machine embodying this invention;Fig. 2, a detail to be referred to; Fig. 3, a vertical longitudinalsection of the machine shown in Fig. 1; Fig. l, a guide to be referredto; and Figs. 5, 6, 7, and 8, details to be referred to.

The main frame-work of the machine is shown as a bcX-like structurehaving side walls a, top plate I), and bottom plate 0. A shaft (1 passesthrough the box-like structure, having its hearings in the side walls a,said shaft having arranged on it a grating-cylinder cl. Thegrating-cylinder, asherein shown, consists of two end plates or frames(Z and the cylinder proper, having the grating-sun face, the said endplates (1 being connected together by bolts d and nuts d. A plate a isarranged in suitable inclined guidcways in the box-like structure belowthe gratingcylinder cl, said plate 6 being perforated for a shortdistance only, and being agitated or moved back andforth to shake it asthe cylinder revolves.

The means herein shown for agitating or moving the plate 6 consists of apin or pins 2, projecting from the cylinder, which strike an ear 3 onthe plate or frame 6, which car rises into the path of movement of thepins. The pins operate to move the plate 6 outwardly, and suitablesprings a, (see Figs. 1 and 2) are provided, one of the ends of whichare attached to the frame-work and the other ends attached to the plate6, which operate to Withdraw or return the plate to its normal condition.

Two boxes, receptacles, or compartments or drawers ff are arrangedbeneath the plate e, and when in use one of the compartments, asf, ispulled out, as shown in Fig. 1, to expose the compartment or drawer fbeneath it.

The top plate I) of the box-like structure is hinged at b, that it maybe raised to permit cheese, or it may be bread or any other suitablematerial, to be inserted or placed in the box beneath the cover on thegrating-cylinder.

The shaft (6 has secured to it a hand-crank d", by which it is revolved.As the shaft (1 is revolved, the material being grated and falling onthe inclined plate 6, the finer par ticles pass through the perforationsthereof and enter the compartment or drawer f, while the coarserparticles follow down the plate and enter the compartment f.

As a means of readily withdrawing the shaft d, that a coarser or finergrating-cylinder may be employed, I have provided the bearing t for theshaft at one end with a flange 1'', cut away or recessed at one sidefrom the edge of the cylinder, in which recess a slide i is dovetailed,said slide being withdrawn by means of the projection and being held inposition by a segment i pivoted at i said segment resting on the upperedge of the slide i A circular saw on is secured to the shaft cl by aset-screw m, said saw being of suitable diameter to project through anopening m formed in the plate I) of the box-like structure, and on saidtop plate a suitable adjustable guide is arranged parallel with the saw,

(see Figs. 3 and 4,) said guide being herein shown as comprising the barm loosely c011- nected to the parallel bars m pivoted to the top plate,a slotted bar m having a thumbnut m, being employed for adjustment. Bymeans of the saw and its guide, cheese or other suitable material may besawed into blocks of any suitable size.

Inclosed in the grating-cylinder dis a knife 12, loosely connected atits lower end at a to a crank-arm n fixed to a shaft 01 provided with asquared end, as shown by dotted lines, Fig. 3,, and which maybe turnedby applying thereto a key-pin 913, (see dotted lines, Fig. 3,) saidkey-pin having a correspondingly-shaped socket in its end to engage withthe end of the shaft 01 The cylinder has an opening a through it, which,when in suitable position, registers with an opening it in the pivotedtop plate I). By turning the shaft n the knife is forced out through theopenings of 92 into the dotted-line position shown in Fig. 1, and whenin such position thecutting-edge of the knife projects slightly abovethe top of the plate 17, so that cheese or other suitable material maybe moved over said top plate by hand, and pieces of any suitablethickness may be shaved off according to the adjustment of the knife.The knife 01. has a pin a, which, when it is moved outwardly to be used,rests upon one of the bolts (1 (see dotted lines, Fig. 1,) connectingthe ends of the cylinder, to thereby serve as an abutment or shoulder,

whereby considerable power may be resisted.

In lieu of the hand-crank If, the apparatus, as an organized machine,maybe run by footpower or by steam-power.

An adj ustin g device is provided for the pivoted top plate 1), (hereinshown as a slotted plate 0,) loosely connected to the plate I) at 0,said slotted plate 0 moving over a set-screw 0 which may be employed tohold it in adjusted position.

In lieu of the saw m, mounted on the shaft d, a disk 0 (see Figs. 7 and8) may be mounted on said shaft, said disk bearing one or more knives,as 0 held in suitable guides, the cutting-edges of said knivesprotruding through openings in the disk 0 As the shaft is revolved,cheese or other material held in the hand or by any suitable holder maybe sliced or shaved off by presenting the material to the face of thedisk, the edges of the knives protruding slightly beyond the face of thedisk, slicing or shaving the material as the disk is revolved.

To claim 1. In a machine for cutting, slicing, and grating cheese, &c.,the revolving gratingcylinder and circular saw, having their bearings inthe frame-work of the box-like structure, the cylinder being within saidstructure, combined with a slicing-knife inclosed in the said cylinder,substantially as de-. scribed.
